Abstract
A workspace device having a body which is collapsible to a collapsed state to fit through a laparoscopic passageway in a body cavity wall, and expandable to an expanded state within a body cavity into which the passageway extends, including: a workspace body having a workspace wall including a plurality of expandable segments defining an internal lumen, and a plurality of radial rigidizers positioned within the wall; wherein in the expanded state: the workspace device extends defining a workspace axis, and has an opening to the internal volume; and the plurality of expandable segments rigidize the workspace body to resist collapse by intra-abdominal forces, and the plurality of radially extending rigidizers positioned within the wall resist radial forces.
Claims19
A workspace device having a body which is collapsible to a collapsed state to fit through a laparoscopic passageway in a body cavity wall, and expandable to an expanded state within a body cavity into which said passageway extends, comprising:
- a workspace body having a workspace wall defining an internal lumen, wherein said workspace wall includes a plurality of vertical expandable segments and at least one radial rigidizer positioned within said wall;
- wherein in said expanded state:
- said workspace device extends defining a workspace axis, and has an opening to said internal volume;
- and
- said plurality of vertical expandable segments rigidize said workspace body to resist collapse by intra-abdominal forces, and said at least one radial rigidizer positioned within said wall rigidize said workspace body to resists radial forces;
- wherein in said expanded state, two adjacent vertical expandable segments contact each other along an interface region having a length larger than 0.2 cm.
